GTC-300 Adjustable Wing
  • Spanning 70 inches, the GTC-500 Carbon Fiber Adjustable Wing is the largest wing available in APR's catalog. With its
    optimized 3D airfoil shape, the GTC-500 is perfect for high speed touring applications and supplies an ample amount of
    downforce without causing excess drag.
  • All GTC Series wings feature an aerodynamic 3D designed airfoil shape to obtain the optimal balance of downforce. This design
    allows for a reduction in drag, yet maintains an ideal level of downforce. Computational Fluid Dynamics (CFD) analysis was
    performed on this wing to support validation of its aerodynamic design. The results of this analysis are available here.
  • Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) or fiber reinforced
    polymer (FRP) composite materials. CFRP models contain pre-pregnated woven carbon fiber sheets for superior strength and
    low weight. FRP models contain woven pre-pregnated glass fiber sheets for high strength at reasonable weight. All CFRP and
    FRP airfoils are made using pre-pregnated composite manufacturing processes (i.e. high-temperature autoclave and vacuum
    bagging) in high-quality aluminum molds.
  • Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish

Warning:
User assumes full responsibility for ensuring proper installation as intended. Professional installation by well-qualified personnel is highly recommended. etc.). To
insure proper function and reliability, APR advises against modification or substitution of any component of the intended installation. Any modification or substitution
of the airfoil, side plates, pedestals, mounting bases, mounting brackets, or hardware included with the wing kit may create unsafe operating conditions and ultimately
cause this system to fail. Substitution of original vehicle manufacturer parts needed for the intended installation (i.e. rear trunk lid or rear hatch) with non-original parts
may also create unsafe operating conditions and ultimately cause this system to fail.

With a span of 67 or 61 inches and a height of 13 inches, the GTC-300 is an adjustable wing that means serious business. The GTC-300 3D airfoil shape allows for optimal
airflow that reduces drag yet supplies an effective amount of downforce. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation
of its aerodynamic design. The results of this analysis are available
here.

Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) or fiber reinforced polymer (FRP) composite materials. CFRP
models contain pre-pregnated woven carbon fiber sheets for superior strength and low weight. FRP models contain woven pre-pregnated glass fiber sheets for high
strength at reasonable weight. All CFRP and FRP airfoils are made using pre-pregnated composite manufacturing processes (i.e. high-temperature autoclave and vacuum
bagging) in high-quality aluminum molds.

Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.

GTC-500 and GTC-200.

Gurney Flaps
Gurney flaps are now available for all of APR's GTC-series (200/300/500) wings. These are super lightweight, made in carbon fiber using the pre-pregnated carbon
process, and conform perfectly to the contours of the GTC-series 3D airfoils. They are easily attached using the included double-sided tape.
The Gurney flap (a.k.a. wickerbill) is an aerodynamic device that was originally pioneered and developed in the 1970s by a racing driver named Dan Gurney.
Unbeknownst to his competition, this device was used to increase downforce while minimizing increase in drag. He found that not only did this device increase the
lift/drag (L/D) ratios, it also increased the stalling angles (so he could operate the airfoils at greater pitch angles). It took a few years for everyone else to catch on to its
purpose, and now, the Gurney flap (or similar device) can be seen in race cars and even airplanes all over the world.
